Test Your 3D Printing Knowledge with Machine Design
What are the most used 3D printing materials?
Thermoplastics and powder metals
Photopolymers and thermoplastics
Photopolymers and powder metals
Inkjet powders polymers and thermoplastics
If you need a material for FDA certification for food or medical applications, you CAN’T use photopolymers and thermoplastics associated with 3D printing.
What are some of the things to watch for in new high-strength materials?
Nothing; these materials are great!
It is difficult to get desirable colors
The sacrificing of another material’s property
None of the above
Does orientation matter when designing parts in which mechanical stresses will be important?
No – even if it was, you can’t get mechanical orientation based on orientation
No – the layers are bonded at a molecular level, so there will be no change in properties
Maybe – there is no data to support this
Yes – layer orientation can present geometries and stress concentrations that may alter properties
What are some applications capable of using 3D print materials?
Mimicking flesh and tissue
Flame retardant certifications
Fixtures and jigs
All of the above
